NP6 HPE and high priority traffic
The NP6 HPE pri-type-max option allows you to set a maximum overflow limit for high-priority traffic. The range is 1000 to 1000000000 packets per second per host queue. The default pri-type-max
By default, the high-priority overflow is applied to the following types of traffic that are treated as high-priority by the NP6 processor:
- HA heartbeat
- LACP/802.3ad
- OSPF
- BGP
- IKE
- SLBC
- BFD
The high-priority setting adds an overflow for high priority traffic, causing the HPE to allow more of these high priority packets.
The overflow is added to the maximum number of packets allowed by the HPE based on other HPE settings. For example, by default, the HPE limits HA heartbeat traffic to l2-others-max + pri-type-max pps, which works out to 200000 + 200000 = 400,000 packets per second per host queue.
